To all whom it may concern:

Be it known that we, BriNo'r AUoUsT SAHLMANN and LILLIAN Snsnnon OAPLE, of Boise city, in the county of Ads, in the State of Idaho, have invented certain new and useful Improvements in Trimmers for the Edges oi Lawns, of which the following is a specification.

This invention relates to an improved lawn edge trimmer.

The object of the invention is to provide a grass entter r trimmer which is adapted to trim the e'dges and cut close to a fence, trees, or buildings, and which is simple in construction and efficient in operation. 7

In the accompanying drawings, Figure 1 represents a side elevation of this improved trimmer; Fig. 2 represents a top plan view thereof; Fig. 3 represents a longitudinal vertical section thereof; Fig. 4 represents an enlarged top plan view of the cutting blades, with the top plate removed Fig. 5 represents a perspective vi cw of the top guard plate detached; Fig. 6 represents a similar view of the top cutting blade detached; and Fig 7 represents a similar view of the bottom cutting blade.

In the embodiment illustrated, a lower stationary cutting plate or blade, 1, is shown having teeth, as 2, an upwardly projecting screw-threaded stud 3 arranged thereon, preferably about the center thereof, and which is provided with upwardly projecting lugs. or tongues, 4 and 5, on its rear edge at its opposite ends for a purpose hercinalter described. Extending from the rear edge of this plate, 1, is a bracket, 6, consisting of two spaced arms, 7 and 8, secured to or made integral with said blade at one end' and connected at their other ends by a crossbar, 9, having a curved or bow-shapcd central portion, 10, to fit over and form a bearing for the handle, 30, hereinafter described. Depending from the opposite ends of this cross-bar are two arms, 11 and 12, having apertures in their lower ends to receive the axle ends, as '13, of a supporting roller, or wheel, 14; The upper part of this cutter comprises a blade, 15, having cutting teeth, as 16, to cooperate with the teeth of the lower blade. This blade, 15, has a longitudinal slot, 17, to fit over and slide on the stud, 3, of the lower blade, 1, and is provided at its opposite ends adjacent its rear edge with slots, 18 and 19, which slide on the lugs, or tongues, 4 and 5. This blade, 15, is also provided at its rearcdge with spaced depending arms, 20 and 21, between which an eccentric, 31, mountcd in the handle, 30, is

disposed and adapted to turn.

the/top cutter blade, 15, and is provided with an upbent central portion, 26, forming a protecting front hood't'or the eccentric, 31. This guard plate is held in The handle, 30, preferably comprises a tubular momber, 32, mounted at one end in the bracket of the lower cutting blade and having connected at its other or outer end a loop-shaped supporting bracket, 33, with a hand grip, 34, at its outer end.

Mounted on a stud in this bracket or frame, 33, is a crown gear, 35, which meshes with the pinion, 36, on the outer end of a rod or spindle, 37, loosely disposed in the tubular member, 32, and extending therethrough. At the lower end of the spindle, 37, is fixed the eccentric, 31, which is disposed between the arms, 20 and 21, of the slotted upper blade, 15, and which, whenrotatcd, reciprocates said blade, 15, longitudinally on the blade, 1, and acts as a clipper to cut the grass. On the crown gear, 35, is secured a crank handle, 38, for turning said gear toopcrate the cutting blades.

In the operation of this device the trimmer is moved forward to the edge to be trimmed and the crank handle, 38, is turned to rotate the crown gear, 35, and through the pinion, 36, with which it meshes, the rod, 37, having secured to its lower end the eccentric, 31. The re tation of this eccentric, 31, causes the blade, 15, to be reciprocated on the fixed lower blade, 1, whereby the lawn may be trimmed closely to a fence or other object.

We claim as our invention,-

1. A lawn edge trinnnor comprising a lower toothed cub ling blade, :1 screu thrcaded stud projecting upwardly therefrom, upwardlycxtendlng lugs arranged at. opposite ends of the rear edge thereof, a, bracket secured to the rear edge of said blade, on upper cutting blade or sickle having end slots engaged with said lugs and A longitudinal slot through which said stud projects, spaced members at the Poll! of said sickle blade, a handle mounted in said bracket and having :1 com :u'l'ungcd to operate botwocu said spucull members, a roller mounted on said bl nckct, and means for rotating said cum to reciprocate said top blade.

2. A luwn edge trinuuor comprlsing a lower toothed cuttingbludu, a screw-tlm-mlc'd stud projecting upwardly therefrom, upwnfilly-extending lugs arranged at. opposite curls at the roar edge thereof, 11 bracket. secured lo the rear edge of said blade, :i rollcr mounlcd in said bracket, an upper cutting blade or sickle bar having cud slots engaging said lugs'aml a longitudinal slot llu'olu:h which said stud projects, spaced members :it the rear oi sold sickle blade, a bundle mounted in said bracket and having a com arranged lo opt-rule lu-lwocu said spucud numbers, a guard plate mounted on sold stud and arranged over the upper cutting blade :llhl having :1 depending lluug'o bearing on said upper blade, a out on suld SCl'UWllllfllHll'll stud to hold said purls lu ll;..':l '.:('l|l .ll|., and menus carried by said b:1u die for rotuliup; suidcum to reciprocate said top bludc.
